Correct Option: 4 - All of them

• Adequacy of the sentence requires that the punishment imposed on the offender is just and proportional to the crime committed.
• The sentence should not be too severe nor too lenient, striking a balance between justice and fairness.
• The court must consider the motive and magnitude of the offense, ensuring the severity of the sentence reflects the gravity of the crime.
• The age, character (including antecedents), and station in life of the offender are important factors, as the court may consider the personal circumstances that could affect the appropriateness of the sentence.
• Therefore, all of these factors are integral to determining a fair and adequate sentence.
